Exchange hybrid add-in on premise problem

Question

I have a hybrid 365 environment with exchange 2016. I am trying to install a barracuda essentials add-in. I go to my on premise environment and go to add-ins and to the store. I log in and try to download but it keeps defaulting to my 365 exchange add-ins. I have tried an unlicensed account for 365as a test and no luck. I have hybrid modern auth set up. When I try to use an account that isn't seen azure ad it can't find account. I have installed the add-in in my 3y5 environment already just can't get it to install in my on-prem servers

Hi @David,

You could try to install the add-in with an personal Microsoft account like an outlook.com account. If you do not have one, you could apply an outlook.com account for free via https://outlook.live.com/mail
